Specification of Letters Patent.

Patented July 7, ram.

Application filed November 1?, 1913. Serial No. 801,443.

To all whom it may concern Be it known that I, Orro LEONARD RAABE, a citizen of the United States of America, residing at Hayes, in the county of Middlesex, England, have invented new and useful Improvements in Movable J ournal-Boxes, of which the following is a specification.

This invention relates to adjustable bearing or journal boxes of the kind that are used in printing machines for setting the impression and that are provided with movable wedges arranged diametrically opposite each other for effecting the adjustment by movement of the wedges individually in opposite directions.

According to my invention I provide the bearing or journal box with means whereby the said wedges can be adjusted simultaneously instead of individually as heretofore thus enabling the setting of the impression to be eifected in a simple, quick and accurate manner independently of the action of springs which have been necessary in certain I previously proposed devices employing simultaneously adjustable wedges.

For the purpose of my invention T'may provide beneath the bearing box, a pivoted arm or lever adapted to move about an axis parallel to that of the printing cylinder whose bearing is to be adjusted. This lever is connected at each of its ends to the wedges through suitable links, one of which is preferably provided with an adjusting device for enabling the wedges. to be initially set so that their operative surfaces bear firmly against the inclined sides of the bearing box, and the adjacent sides of the recess or cavity in which the box is mounted. Suitable means are provided for imparting longitudinal movement to one of the wedges which movement is transmitted to the same extent but in the opposite direction to the other wedge through the aforesaid pivoted arm or lever, thus effecting the simultaneous movement of the wedges for obtaining the requisite adjustment.

In order that the said invention may be clearly understood and readily carried into effect the same will now be described more fully with reference to the accompanying drawings in which Figure 1 is an elevation of the improved bearing or journal box applied to one of the printing cylinders of a printing couple for setting the impression. Fig. 2 is an underside view of Fig. 1. Fig. 3 is a transverse section taken approximately on the line 11 of Fig. l and viewed from the right.

A is the adjustable bearing or journal box in which is mounted the spindle of one of the printing cylinders C C forming part of the printing couple.

B is the cavity formed in the frame B of the machine for the reception of the said box A.

B is a detachable cover or keep secured to the framing of the machine by bolts Z) I).

D D are wedges which cooperate with the inclined sides a a of the bearing box and the vertical sides or walls of the cavity 13* to effect the displacement of the bearing box bythe vertical movement of the wedges in opposite directions.

E is the arm or lever pivoted at its mid point e to the framing of the machine at the base of the cavity B and connected at each of its ends 6 e to the wedges D D through links F F. One of the said links (viz: F in the example shown) is made in two portions which are connected together by a right and left hand threaded spindle G having an enlarged portion 9 to enable the spindle G to be conveniently rotated in order to move the wedge D in either a downward or an upward direction for initially setting it and causing both wedges to bear firmly against the inclined sides a a of the bearing box and the vertical side walls of the cavity B". The wedge D is internally screw threaded and a correspondingly screw threaded member or spindle H. is mounted.

in the cover or keep B so as to engage thethreaded portion of the said wedge.

In order to prevent axial movement of the threaded member H it is provided with a shoulder h bearing on the top of the cover B and with a nut 7?. bearing against the underside of the said cover the said nut being retained in position by a pin 71?. The threaded member H has a suitable shaped head 7& for enabling it to be conveniently rotated the said shoulder h advantageously forming part of the said head. On rotating the said member in one direction the wedge D will move upward and will displace the lever E about its pivot e in a direction to move the wedge D downwardto the same extent as the wedge D moves upward. These simultaneous movements of the Wedges cause the bearing box to be displaced in a direction toward the printing cylinder C thereby diminishing the distance existing between the two printing cylinders C O and increasing the pressure of the cylinder 0 against the cylinder G. On rotating the member II in the opposite direction the Wedges are caused to move simultaneously inthe opposite directions to those above stated. and. the bearing box becomes displaced in a direction to increase the distance existing between the two cylinders thereby diminishing the pressure of the cylinder 0 against the cylinder 0.

Although the above stated means for operating the wedge D will be found very convenient in practice, any other appropriate means may be used for the purpose Without departing from the invention,

In order to lock the member H in its adjusted position the periphery of the head if thereof may be formed with serrations or notches with. which a spring finger h attached to a convenient part of the cover B engages thereby preventing unintentional rotation ofv the member I-I while the machine is working; a similar locking device may also be provide to hold the enlarged portion 9 ofthe divided link F in its initially adjusted position.

I wish itto be understood that I do not desire to limit myself to the aforesaid pivoted arm or lever for effecting the simultaneous adjustment of the wedges except as hereinafter specifically claimed, inasmuch as any appropriate devices may be used.

What I claim and desire to secure by Letters Patent of the United States 1. In an adjustable bearing or journal box, the combination with movable wedges arranged on opposite sides of the bearing, of a pivoted arm coupling. said wedges together and means for imparting movement to said arm. Y

2. In an--adjustable bearing or journal box, the combination with movable wedges situated on opposite sides of the bearing, of a centrally pivoted arno, coupling said wedges together, and means for imparting rocking movement to said arm.

3. In an adjustable bearing or journal box, the combination with movable wedges situated on opposite sides of the bearing, of a -centrally' pivoted arm coupling said wedges together and means for imparting longitudinal movement to one of said wedges. v

4:- In an adjustable bearing or journal box, the combination with movable wedges situated on opposite sides of the bearing, ofv a pivoted arm coupling said wedges together, a screw threaded member mounted in-the bearing box and engaging a corresponding screw threaded portion of one of the said wedges and means for imparting rotary movement to said screw threaded member.

5. In an adjustable bearing or journal box, the combination with movable Wedges situated on opposite sides of the bearing, of a pivoted arm coupling said wedges together, a screw threaded member mounted in the cover of the bearing box and engaging a corresponding screw threaded portion of one of saidwedges, means for-imparting rotary movement to said screw threaded member and means for locking said member. I I

6. In an adjustablebearing or journal box, the combination with movable wedges situated on opposite sides of the bearing, of a pivoted arm coupling said wedges together, a screw threaded member mounted in the cover of the bearing box and engaging a corresponding screw threaded portion of onev of the said wedges, means for imparting rotary movement to said screw threaded member, a serrated portion on the latter and a spring catch engaging with said serrated portion.

7. In an adjustablebearing or journal box, the combination withmovable wedges situated on opposite sides of the bearing, of a pivoted arm coupling said Wedges "together, and means for imparting movement to said arm, the connections between said pivoted arm and said wedgesbeing adapted to give laterally in the operation of said arm.
